SPECIFICATION forming part of Letters Patent No. 274,794, dated March27, 1883.

Application filed February 10, 1883. (No model.) 7

To all whom it may concern.-

-Be it known that I. W. J. F. LIDDELL, of Charlotte, county ofMecklenburg, State of North Carolina, have inventeda new and use- 5 fulImprovement in Shaft-Hangers, of which means whereby the shaft-box maybe readily and easily adjusted in either a vertical or lateraldirection, or both, as may be required.

It consists in a hanger composed of a cappiece having pendent parallelarms, provided about midway of their length with a slotted cross-bar,whereby said hangeris adapted to receive suspension-bolts passingthrough and pendent from the cap of the hanger, and also passing throughthe slotted cross-bar, said bolts sustaining the shaft-box andpermitting the slot in the said cross-bar allows lateral adj ustment ofthe said bolts and box, the latter being adjusted and held in positionby screws for that purpose.

It also consists in providing the upper half of the shaft-box with aguiding-tongue passing through the slotted cross-bar, for guiding andsteadying said box, and in adjustingscrewsin the cros's-barfor clam ping said tongue firmly therein; and, lastly, it consists in a combineddrip-cup and nut-lock for catching the oil as it drips from theshaft-box, and at the same time serving by its construction to lock thenuts on the ends of the suspension-bolts, said cup having ahinge-connection at each end-with the shaft-box, adapting it to be swungdownward on either of its pivots, when desired, as hereinafterexplained.

In the accompanying drawings, Figure 1 is a side elevation, partly insection; and Fig. 2 is a vertical section through the shaft-box andhanger.

A represents the cap of the hanger; A and A the pendent parallel arms,connected by the slotted cross-bar D. ed with holes or slots for thepassage of the bolts securing said cap and hanger to the ceilit to beadjusted in avertical direction, while.

The cap A is providends let into sockets or recesses therein, and

the perforations in the cap, through which said bolts 0 0 pass, areslightly expanded in width at their lower ends to permit lateral play ofsaid bolts.

B represents a shaft-box composed of two parts, the upper part, B,having a tongue, B extending upward through the slotted crossbar D,serving, when the shaft-box is being adjusted, to guide the said box andgive greater rigidity to the hearing when in the desired position, andthe lower part, B, having on its lower face slotted .lu gs or ears I) b,fora purpose that will be hereinafter explained. The

suspension-bolts O G by preference pass through the shaft-box, and areprovided heneath said box with nuts 0 c, on which it rests. Similarnuts, 0 are provided on the suspension-bolts, above said shaft-box, forpreventing upward thrust of the latter, and these'latter nuts are lockedin place, when properlyadjusted, by means of jam-nuts 0 Thus it will beapparent'that the shaft-box B may readily and easily be adjusted up 'ordown on the suspension-bolts, and the parts thereof may also beadjusted, in case of wear, to fit the shaft working therein, by means ofthe nuts 0 c below the box, the corresponding nuts, 0 above the 'box,and thejam-nuts 0 To affordlateral adjustment of the shaft-box,adjusting-screws a a, having lock-nuts a a are provided in the pendentarms A A of the hanger, withtheir inner ends resting against thesides ofthe shaft-box, as shown in Fig. 1. The suspension-bolts being free toswing, the box can be adjusted laterally and held firmly in place, whenso adjusted, by means of screws act and lock-nuts a (1.

When it is desired to place the shaft in its bearings, the upper part,B, of the shaft-box ICO the lower part, B of box B removed and the shaftraised into place without disturbing the upper part of the shaft-box.

E represents the drip-cup, and by reference to Fig. 2 the manner of itsattachment to the shaft-box will be understood. Said cup is providedwith tongues e c on its periphery, adapted to fit into slots in thelugsorears 111), above referred to. Pins f and f pass through perforationsin the said lugs b b and tongues 6 6 as shown in Fig. 1, thus forming ahinge-connection between the shaft-box and drip-cup.- The pinsff' areL-shaped, the shorter side of the angle being in the form of a ring orloop, which drops by its own gravity within the drip-cup, the latterholding it against accidental displacement. The drip-cup E is providedwith vertical projections on either side, as shown at e and e in Fig. 1,and of the form shown in Fig. 2 at 6, extending up on the outside of andresting against thenuts c c on the suspension-bolts G O, and by theirrelation thereto serving "ery eii'ectually to lock the said nuts'andprevent their escape.

It will be apparent that the hereinabove-described hanger is adapted tobe applied as well to a wall or floor or any other desired point as to aceiling by slight modifications in form adapting it to such places.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is- V 1. Ashaft-hangerbracketcomposed ofacap, parallel arms pendent therefrom, and a slottedcross-bar connecting said parallel pendent arms, substantially asdescribed and shown.

2. A shaft-hangerhaving parallel armspendent from the cap thereof and aslotted crossbar connecting said arms, in combination withsuspension-bolts sustaining the shaft-box, and allowing vertical andlateral adjustment thereof, substantially as described.

3. The combination, with the shaft-box sustained by means ofsuspension-bolts pendent from the hanger, of a. guiding-tongue, Bextending through the slotted cross-bar of said hanger, and theclamping-screws d and 61'', substantially as and for the purposesdescribed.

4. The combination, with the box of a shafthanger, of a combineddrip-cup and nut-lock, for catching the oil and locking the nuts on thesuspension-bolts, substantially as described.

5. The drip-cup E, having a pivotal connection at each end with theshaft-box, in connection with removable pivotal pins adapting the cup tobe swung downward on either pivot, substantially as described and shown.

6. The combination, with the drip-cup, of a pivotal pin provided with apendent loop or arm adapted to drop by its own gravity within thedrip-cup, for preventing accidental displacementof said pin.

In testimony whereofI have hereunto set my hand this 5th day ofFebruary, A. D. 1883.
